WebGL Shaders & GPU Performance

WebGL enables rich interactive visual mockups on the web, but unoptimized render loops can freeze browser threads.

GPU Compile Budgets

WebGL custom shaders compile at runtime, meaning your shader size directly dictates initial scene load times.

// GLSL Shading
uniform float u_time;
varying vec2 v_uv;

void main() {
  vec2 uv = v_uv;
  vec3 col = 0.5 + 0.5 * cos(u_time + uv.xyx + vec3(0, 2, 4));
  gl_FragColor = vec4(col, 1.0);
}

Avoid heavy computations in the fragment shader. Utilize vertex attribute buffers to scale render efficiency.
